JOHN N. GOULD, OF FREDERICKTOWN, OHIO, ASSIGNOR TO THE F. B. ZIEG MFG.

COMPANY, OF FREDERICKTOWN, OHIO.

ROAD-GRADER.

Application filed March 5, 1915, Serial No. 12,858.

To all whom it may concern:

I Be it known that 1, JOHN N. Goon), a citizen of the United States, residing at Fredericktown, in county of Knox and State of Ohio, have invented certain new and use ful Improvements in Road Graders, of

which the followin is a specification.

My invention re ates to an improvement in road graders for road-building and ditching, and the object is toprovide improved mechanism for more perfect control of the machine, and more especially the mold-board or scraper, means being provided within the ently of the other; and for swinging therear axle to facilitate the turning of the machine to its work; and for shifting the rear end of the frame laterally with respect to the axle, in other words endwise of the axle. .1 In the accompanying draw1ngs:

through the main frame showing the cross- 'bar and casting which is adjustable thereon;

Fig. 8' is a longitudinal vertical section through this cross-bar; and

Figs. 9, 10, 11 and 12 are details.

The numerals 1, 1, represent the longitu dinal I-beams, of which there are two, of the machine. These extend from front to rear and throughout the length of the ma- Figure 1 is a view in perspective from one I Specification of Letters Patent.

chlne, being supported at the forward end on the forward axle 2, and'at the rear end by the rear axle 3. They are bowed upwardly through the center, as shown in Fig. 1, and at the rear they are securely bolted to' the sides 1 of the platform 5 as well as to the sides of the standards 6, 6, erected from the forward end of the platform.

A connecting-bar 7 extends across and is securely bolted to the upper edges of the I-beams 1, 1, a little forward of the stand- "ards 6, 6, and just forward of this connectlug-bar 7 1s a cross-bar 8 preferably of angleiron, the ends of which are bolted to the inner faces of the I-beams 1, 1, as shown in Fig. 7.

The scraper or mold-board frame comprises two converging angle-irons 9, 9, which meet at the forward end, of the machine where they are supported by the front axle 2; and at the rear end these angle-irons 9, 9, are bolted to the U-shaped frame 10, the s des of which extend upwardly on either slde of the longitudinal I-beams 1, 1, and the upper ends of this U-shaped frame are pivotally supported on the cranks 11, 11, on

the forward ends of the crank-shafts 12, 12, which latter are journaled in the upper ends of the standards 6, 6, and in the uprights 1,3, 13, erectedfrom the angle-iron cross-bar 8. 'Th'ese shafts 12, 12 are provided with worm-wheels 14, 14,. on their rear ends, which latter are turned through the mediu of worms 15, 15, and these worms are turned by means of the large hand-wheels 16, 16,

disposed parallel with each other and with the I-beams 1, 1, a little above the platform 5 within reach of the operator.

The mold-board or scraper 17 is held by yoke 18 to the turn-table 19, and the latter is turned by meansof the shaft 20, said shaft having a hand-wheel 21 on its rear end, by

which the operator turns it, and a pinion 22 on the forward end which engages a rack 23 on the turn-table 19 for adjusting the angle of the scraper or mold-board.

It is also possible -to adjust the entire frame -9 and 10 laterally or crosswise of the machine to regulate the position of the scraper or mold-board. A casting 24 is slidably mounted on the cross angle-iron 8.

Y which a rod 26 is hung, and this rod 26 ployed for shlfting and locking t ese extends to one of the lower corners of the U-shaped frame 10.

which shaft is journaled in the casting-24, and its teeth engage the teeth of a rack 29. So as the shaft is turned, the casting 24 travels to the right or to the left on the angle-iron cross-bar 8, and with it the frame 910 moves either to the right or to the left. The shaft 28 has a universal joint 30 in it, and its forward end is provided with a handwheel 31 by which the operator turns it to the right or to the left.

A spring-actuated slide-bolt 32. is slida'bly connected with the casti 2'4, and is adapted to lock" the casting y passing through one of the holes 33 t erefor in the angle-iron cross-barS, and this spring-actuated bolt 32 is controlled by the cam-lever 34 pivotally connected with the bolt, and having a rod 35 connected with 1t, a; pull upon which causes the withdrawal of the bolt by causing the cam face 36 of the lever 34 to fulcrum upon the surface of the casting 24, thus withdrawing the bolt, and the spring acts to lock the casting to the angleiron cross-bar 8 when the holes 33 and 33 are in registry. Other means mi ht be (gripsi, a and this is but one of many t at mlg t be used.

Means is provided for moving the rear end of the frame laterally with respectto the rear axle 3, that is to say lengthwise of the axle. This isaooomplished through the rack 37 on 'the rear of the axle 3, andthe verti cally-disposed-shaft 38, which 'has a pinion 39 thereon, the teeth of which engage the rack. This shaft 38 is located at the rear left-hand corner of the machine Within reach of the operator, and has a hand-wheel 40 by which it is turned. By this means,

the entire rear end-of the/machine may be shifted with respect to the rear axle by means of the wheels 41, 41, which is sometimes .very desirable in the operation of ditching and grading.

Again, it is possible to swing the rear axle at an angle to the frame, and this may be accomplished through the worm 42 on the lower end of the vertical shaft 43 at the rear right-hand corner of the frame, and which shaft has a hand-wheel 44 on its upper end within reach of the operator. This worm 42 engages a worm-wheel 45, and secured to this is a lever 46, and from which a link 47 extends to the axle 3, so that as the wheel 44 is composed of a plurality of teeth 48, eight A gear-wheel 27 is keyed on a shaft 28, the forward end of of which are shown. These teeth are sharpened at each end, and, reversible, and provided with several notches 49, in which the clips 50 (two of which are shown) engage, these clips being used as a means for bolting the teeth to the cast-iron frame 51. The latter is bolted to the rear ends of the angleiron bars 52, 52, which latter are pivoted at the forward end of the machine over the front axle 2. The rear ends of the angleiron bars 52, 52, are pivotally connected to the lower ends of the hangers 53, 53, one on either side of the machine, and the upper ends of these hangers are pivotally connected with levers 54, 54, on the worm- Wheels 55,55, and these are engaged and turned by the worms 56, 56, on the forward ends of the horizontal shafts 57 57 Hand wheels 58, 58, on the rear ends of the horizontal shafts are provided within reach of the operator for turnin them; 4

In this way the scari er is raised or lowered bodily, or more at one end than the other, as may be desired. V

The tongue 60 is capable of being swung to the right or left, and held in any position therebetween, and for this purpose itis pivoted coincident with the center of oscillation of the forward axle 2. A worm -wheel 61 is secured on the tongue, plate 62 is secured to this wormwheel, and links 63, 63 are pivotally connected to the ends of the; plate 62, at their forward ends, and at their rear ends to the front end of the frame. A worm 64 engages the worm-wheel 61, and a rod 65 having a universal joint 66 therein carries this worm at its forward end, and has a hand-wheel 67 at its rear end, whereby the rod 65 is turned to turn the worm' 64' and worm wheel 61, and in that wa swing the 106 tongue or pole to the right or le t.

In this way, it will be) seen that all of the adjusting means are located within reach of the operator riding on the platform 5, so that he has complete control of every part of 110 the machine. I

More or less slight changes might be resorted to in the form and arrangement of the several parts described without departure from the spiritand scope of my invention, and hence I do not wishtobe limited {)0 the exact construction herein setforth,
